TO ALL WHOM IT MAY CONCERN:

Be it known that I, H. WOODMAN, of. Saco, in the county of York, andState of Maine, have invented al new and improved Shingle-Machine; andthat thev following description, takbn in connection with theaccompanying drawings, hereinafter referred to, forms a full and exactspecification of the same, wherein I have set forth the nature andprinciples of my said improvements by which my invention may bedistinguished from all others of a similar c lass, together with suchYparts as I c laim, and desire to have secured to me by Letters Patent.

This invention relates to a new and improved machine for sawing andplaning shingles; and it consists of a rotary .feed-table, circular saw,and rotary planer, all arranged and combined to operate in the mannersubstantially :rs-hereinafter set forth. Itthe accompanying sheet ofdrawings- AFigure V1 is a side view of my invention. Figure 2, a plan ortop view of the same. `'Figure 3, an enlargedsection of the feed-wheeltaken in the lino zz, fig. 1; and Figure 4 isthe same view as fig. 3,with the screw-wheel shaftin a different position. Similar lettersoffreference indicate corresponding parts.

A represents a framing, which 'may beV const-ructed in any proper mannerto support the working parts. B is a horizfontal shaft, placed on theupper part of the framing A, and having a circular saw, O, at one end ofit. D is a horizontal shaft at one end of the framing, and having atoothed wheel; E, at.one end of it, into which a pinion, F, gears, saidpinion being at one'end of a horizontal shaft, G, in the lower end ofthe framing. Th'e shaft G is driven by a belt, I-I, from the saw-shaftB,`said belt passing around a lever-pulley, I, on the shaft G, which isconnected with the shaft by a clutch, a, the pulley I being moved so asto be engaged with or disconnected from the shaft by means of a lever,J, (see fig. 2.)V The wheel E constitutes thc feed-table, and it has anumber of rectangular openin'gs in it to receive the bolts from whichthe shingles are cut. Three of these openings are shownin fig. I, butmore or less may be used. At each end of each of these' openings thereis a grooved cylinder, K, having a pinion, L, at one end, into whichscrew-wheels M M on a shaft, N, gear, (see more particularly Eg. 3,) andat one end of the shaft N there is a dog, O, composed of four radialarms b. One of the Vgrooved cylinders K is tted in an adjustable frame,I), which is moved or actuated by a lever, Q, the latter being held inposition by a segment-rack, R, on the wheel. A spring, S, on this lever,bears against the frame P, as shown in fig. 1. Thisv adjusting-movementof one of the grooved cylinders is necessary in order that bolts ofdiiferent lengths may be secured 'between the grooved. cylinders, andthe spr-ing S admits 'of one of the grooved cylinders yielding tocompensate for any irregularity in thc length of a bolt. Thescrew-wheels M M are each provided with two spiral anges, c c, a portionof each flange having a spiral, I, and a circumferential part, 2, asshown invfig. 4. On the upper part of the framing there isla projection,d, for the dog O to strike against as the wheel or feed-table E rotates,said projection extending over the upper part of the feed-table.

On the upper part of the framing A there is secured a metallicadjustable frame, T, having a shaft, U, secured in it. To one end ofthis shaft there is secured a rotaryY planer, V, which may beconstructed in any proper manner. A cutter or chisel, e, at each end ofan arm, W, will answer the purpose.

When the machine is in operation, the wheel or table E rotates inthedirection indicated by the arrow I, and the saw C cuts a shingle fromeach bolt, and the planer V smooths4 the surface of each bolt as theypass from the saw, on-e side of each shingle being planed, whichofcourse is all that is necessary. The bevel or taperis giventhe'shingles by the feed-mechanism, which presents the bolts to the saw,cach bolt being fed inward inconsequence of an arm, b, of the dog .0,'coming in contact with the projection d, the shaft N being turnedthereby a quarter of a revolution.l Both ends of the bolts are not movedthe same distance at each feed-movement, the yends being movedalternately, one more than the other, in order that the shingles may becut in taper form. 'This is elected by having the spiraland'circumferential parts 1-2, of the ilanges C, of the screwfwh'eel M Marranged' in such relation with each other as vto cause the' differenceof movement specied, theends of the bolts being moved alternatelyinward, towards the cutting-plane of the saw, and the shinglesconsequently sawed in proper taper form. I design t'o have the shingles,as they are cut, fall upon an elevatorapron, X, which conveys them up toan edging-saw, Y, at one side of the framing.

Having thusfdescribed my invention, what I claimas new, and'desire tosecure by Letters Patent, is-

l. revolving table, with its feeding and s ecuring-tnechanism,`constructed vsubstantially as described, in combination with the rotaryplaner .V and saw C, as and for the purpose specified.
